Answer:
Step-by-step explanation:
Let the equal number of hours be represented by variable H;
The two equations will be as follows;
Jack; 40 +30H
Mark; 50 +25H
Next, equate them;
40 + 30H = 50 + 25H
30H - 25H = 50 - 40
5H = 10
H =10/5
H = 2hrs
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30H = 40 + (30*2)
=40 + 60
= $100
Answer:
m=4
Step-by-step explanation:
We are to find the value of m in the question
1.75+0.75m=4.75
Let's start by substrating 1.75 from both sides
0.75m=3
We will have to make m the subject of formula by dividing both sides by 0.75
m=4
Therefore the final answer for m is 4
Answer:
1200
Explanation:
y represents the estimated population
t represents the number of years.
The equation that predicts the population after t years is given as:
Substitute t = 3/2 into the equation
The closest valuie to the value of y is 1200
